VEHICLE-WHEEL TIRE. e

. Appucauon sled January 1s, 1927. seria1 No. 161,826.

One object of our invention is to provide a highly ellicient mechanical substitute for airin hollow resilient tires.

It is also an object of the invention to 5 provide a structure of the character indicated that may be quickly assembled independently of the tire and inserted bodily therein.

It is a further object of the invention to provide a device of the character indicated that will be economical in construction, simple in form, and highly efficient in its practical application.

In the drawing:

Figure 1 is a side elevation of a portion of the device as arranged for insertion in a tire.

Figure 2 is a sectional view on line 2 2 of Figure 1 showing said portion inserted so in a tire mounted on a rim.

Figure 3 is an elevation of one of the spring supporting buttons.

Figure 4 is a perspective view of one ofthe supporting plates.

Referring more particularly to the drawing, we show at 1 a vulcanized rubber tire, the interior of which is rectangular in transverse cross-section as at 2 with rounded corners as at 3. The tire is fitted upon a rim as 4 in any suitable manner.

At 5 is shown an annular rubber ring having va transversely flat outer perimeter as 6 and concave side portions as at 7 to engage the parts 3 of the tire.

In constructing the preferred form of the invention we provide two similar structures designated in general by the reference characters A and B separated by a heavy rubber band 8. The structure A has an 4o outer diameter substantially equal to the outer diameter of the tire chamber, and the structure B has an inner diameter substantially equal to the outer diameter of the ring 5, so that when assembled as shown with the ring or band 8 inserted between the two structures the whole completely fills the tire chamber.

Each of the structures A and Bis built up in the following manner. At 9 and 10 are two spaced and concentrically arranged bands of heavy leather having a width substantially equal to the width of the tire chamber. Arranged crosswise of the band 9 and on the outer surface thereof and in spaced relation to each other, are a plurality of plates 11. Similarly arranged on the inner surface of the band 10 are ar plurality of lplates 12.

At 13 we show a plurality of buttons having basal surfaces of reduced diameter as at 111-, and each button having a pin 15 projecting outwardly from the last mentioned surface to engage anorifice as 16 in a plate l1.

In assembling the structure, the bands 9 and 10 are first fitted with the plates 11 and '12 in the position described, the buttons e set forth and arranged in concentric relation to 4each other, a spring 17 is slipped on to each pair of opposing buttons as shown, thereby making the unitary structures A and B,

In completing the assembly, the part A is first placed in position in the. tire and then the band 8 is put in place, this being followed by the part B and then the ring 5. When the assembled tire structure is placed in position on a rim it is ready for use.

By means of this construction a wide bearing surface is secured the full width of the wheel rim, and the spring resistancefis uniform throughout the whole width. Furthermore, by means of this construction a large number of springs may be economically disposed about the circumference of the tube thereby satisfactorily distributing the stresses and strains to which a tire is naturally subjected.

The construction is economical because besides the bands of slightly different diameter there are only two other elements of different form, namely the buttons and the plates, which require special manufacture.

It is to be understood, of course, that while we have herein `shown and described but one specific embodiment of the invention, changes in form, construction, and method of assembly and operation may be made within the scope of the appended claims.

Ve claim:

1. In a structure of the character described, a pair of spaced and concentrically arranged lexihle bands, a plurality of spaced plates positioned lo-n the outer sur- 'face of one hand and the inner surface of the other and extending crosswise thereof, a plurality of pairs of opposed buttons mounted on the opposing surfaces of said bands and provided with pins extending through said hands and riveted to said plates, and .a helical spring engaging each pair of opposed buttons.

2. ln a structure of scribed, a casing provided With an annular the character de-y chamber rectangular in transverse cross-section, a pair of -annular resilient structures lmounted therein With a flexible band positioned between the same, each ystructure comprising a pair of spaced and concentrically 'arranged kiiexilole hands, a plurality of pairs of opposed buttons mounted on the opposing surf-aces 'of Said iban/ds, and a helical spring connecting each pair of opposed buttons.
